Seriously, sometimes the HL can get goofy and not learn your original remote. In such a case, follow the directions to clear the HL completely. Then follow the directions to train the HL as in non-rolling code. It can take 30 seconds before you see something happen while you are pressing the button.
Then once the HL is trained, you then train your opener to accept the code from the HL following the directions for your opener in adding a new remote.
